PhysicsEasysingle choice

A wavefront is represented by the plane $y = 3 - x .$ The propagation of wave takes place at

Options:

Answer:

Solution:

The propagation of ray takes place in

perpendicular direction of wavefront.

Here, $m_{1} m_{2} = - 1$

$m_{1} = s l o p e o f w a v e f r o n t = - 1$

$m_{2} = S l o p e o f r a y$

$(- 1) m_{2} = - 1 \Rightarrow m_{2} = 1$

$\tan θ = 1 \Rightarrow θ = 45 °$
